Expand the right side:


Notice that 98 = 2 * 7 * 7, so we have
and
.
Then

and

We divide 40 by 1/2:-
40 / 1/2 = 40 * 2/1 = 80 answer
Answer:
a = 
Step-by-step explanation:
Given
ak = v + w ( isolate a by dividing both sides by k )
a = 
Answer:
I think the answer is 21
Step-by-step explanation:
The answer is 21 because we can simple reduce 26/39 = 2/3. And now that you have done that all we need to do is find what 14/w = 2/3 this is quite simple as we just have to mutiply the 3*7 to get 21 as your answer. I don't know if this is correct or not but this is my best answer.
